Fetuin, Fetal Bovine Serum is a liver-secreted 64 kDa plasma glycoprotein isolated from fetal bovine serum. Fetuin, Fetal Bovine Serum inhibits trypsin activity and promote cellular attachment, growth, and differentiation[1][2].

In Vitro

Fetuin, Fetal Bovine Serum is often an important supplement to many serum-free media[2].
? Fetuin is an acidic glycoprotein with three N-linked and three O-linked oligosaccharide chains, whose terminal sugar residues are rich in sialic acid (N-acetylneuraminic acid), contributing to its net negative charge[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
